As early as more than 100 years ago, scientists began to study the relationship between height and longevity. is a short man alive or tall?
A recent study by scientists in the United States found that men under 1.5748 metres are the longest. The researchers found that shorter men were more likely to have a protective longevity gene called “FOXO3”. This gene is a dwarf in the early stages of development, making life longer. In addition, short men may have lower blood insulin levels and may have a lower risk of cancer .
The Chinese Institute of Gerontology has tested 100 people over the age of 90 and found that the average height of men is 1.50 m and that of women is 1.40 meters.
Similar phenomena exist in the animal world. Generally smaller animals, such as mice and small monkeys, tend to live longer, and smaller Asian elephants are always longer than larger African elephants.
So is height and longevity really related? What factors affect life expectancy? Today we’ll get up and see!
What is height determined by?
Height refers to the vertical from the top to the ground, generally in centimeters (cm) as a unit, also used in meters (m). Both congenital and acquired environmental factors have an important effect on human height, but about 90% is dependent on genetic inheritance.
Children are likely to be tall if their parents are tall. Scientific research has found that HMGA2 ‘s genes are one of the genes that control height, and other height genes are yet to be found.
Who determines the life expectancy?
Life expectancy refers to the time of the organism’s survival from birth through development, growth, maturation, aging and death. The length of human lifespan is influenced by many factors.
Genetic, environmental factors, gender, lifestyle (such as diet, nutrition, sports, etc.), emotional personality, medical and health conditions will have an impact on people’s life expectancy.
Does height and longevity really matter?
Biologically speaking, there are mainly the following possibilities.
Shorter people had lower levels of insulin and insulin type one growth factor (IGF-1).
Shorter people have a higher ratio of heart and lungs to body weight and less heart and lungs.
Shorter people have fewer ventricular hypertrophy and high blood pressure than tall men.
Shorter people have lower rates of death associated with high blood pressure, coronary heart disease , and cerebrovascular stroke because of the relatively low BMI (body mass index).
Living habits affect longevity more than height
Man’s height cannot be changed, nor does a tall man worry. The effect of height on longevity is not straightforward, but increases the likelihood of certain diseases. Do not care about the size and height, healthy lifestyle is the most important factor to determine the length of life.
1, Control diet
Low salt and low fat diet, proper intake of fresh fruits and vegetables, staple food to achieve the thickness and mix, increase soy products, eat less candy, cakes, drink less or not drink.
2. Regular movement
It is recommended to choose aerobic exercise, such as jogging, swimming, cycling, etc.
3. Good Social
Good interpersonal relationships can help relieve stress and improve the immune capacity of the body.
4. Healthy Mood
Avoid anger, sadness, worry, anxiety, fear and other negative emotions, positive emotions and emotions, can promote the body to secrete the hormones and enzymes conducive to longevity, enhance the ability to prevent disease and anti-aging.
5, adequate sleep
Ensure 7-8 hours of sleep per night, daytime siesta for half an hour or so advisable, preferably not more than 1 hours. A good nap habit of people, immune function than not to take a nap, and not easy to suffer from coronary heart disease, hypertension and other diseases.
